Hi, i have a samsung sgh-d900 slider phone, and i noticed after the first couple weeks my slider felt quite loose. I looked on the internet, and many people seem to have the same issue. I talked to my friend, and he said that his was loose to after the first few weeks, but then it tightened up as he used it more. Well, all of last week i didnt have the loose slide problem, but just yesterday, it felt wobbley again. I know its not that big of a deal, but i like to make sure my things are in perfect condition. other people i have read returned it, but the same thing happened later on. Is this a normal part of the d900? or anyone else have a similar issue?

thanks.
